Installed the system but can't boot

Hello,

I followed the Opencore guide and installed Catalina. But I can't boot, it's stuck here:

Specs: MB: ASRock Fatal1ty 990FX Professional
CPU : FX8350
GPU: PowerColor Radeon HD5670 (UEFI Support added)

Typical of a graphics configuration problem.
You should disable the Serial port(s), they are known to cause problems with graphics drivers.

If you are using Radeon HD5670 graphics then you should correct your profile and remove the misleading GeForce GT 430.

You should also check that Radeon HD5670 graphics are actually supported in Catalina.
